摘要

Ormerod and Mounfield [P. Ormerod, C. Mounfield, Power law distribution of duration and magnitude of recessions in capitalist economies: Breakdown of scaling, Physica A 293 (2001) 573] and Ausloos et al. [M. Ausloos, J. Mikievvicz, M. Sanglier, The durations of recession and prosperity: Does their distribution follow a power or an exponential law? Physica A 339 (2004) 548] have independently analyzed the duration of recessions for developed countries through the evolution of the GDP in different time windows. It was found that there is a power law governing the duration distribution. We have analyzed data collected from 19 Latin American countries in order to observe whether such results are valid or not for developing countries. The case of prosperity years is also discussed. We observe that the power law of recession time intervals, see Ref. [1], is valid for Latin American countries as well. Thus an interesting point is discovered: the same scaling time is found in the case of recessions for the three data sets (ca. 1 year), and this could represent a universal feature. Other time scale parameters differ significantly from each other. (C) 2008 Elsevier B.V. All rights reserved.

Ausloos，J。Mikievvicz，M。Sanglier，衰退和繁荣的持续时间：它们的分布遵循幂法还是指数法？ Physica A 339（2004）548]通过不同时间段内GDP的变化独立分析了发达国家衰退的持续时间。发现存在一种控制持续时间分布的幂律。我们分析了从19个拉丁美洲国家收集的数据，以观察这些结果对发展中国家是否有效。还讨论了富裕年份的情况。我们观察到衰退时间间隔的幂定律，请参见参考资料。 [1]对拉丁美洲国家也有效。因此，发现了一个有趣的问题：在三个数据集出现衰退的情况下（约1年），发现了相同的缩放时间，这可能代表了一个通用特征。其他时标参数彼此之间存在显着差异。 （C）2008 Elsevier B.V.保留所有权利。
